[PATCH 3/3] arm64: zynqmp: Add EBDEE EdgeBoard FZ3A development board

[Pufan Jin]

The EBDEE EdgeBoard FZ3A is a compute carrier board built around the
MYIR MYS-CZU3EG SoM with a Zynq UltraScale+ XCZU3EG.

Enable the board peripherals wired to the PS, including Ethernet, I2C,
storage, PCIe, USB, DisplayPort, UARTs, and AMS temperature sensing.

No MDIO bus? No phy-handle?

Hi Krzysztof,


Thank you for pointing this out. "EBDEE" was an improper local acronym
derived from "EdgeBoard Developer Edition".

The actual commercial brand and manufacturer of the board is ALINX
(Shanghai Xin'yi Electronics Technology Co., Ltd.). The official
company website is:
https://www.alinx.com/

I have dropped the "ebdee" prefix and replaced it with "alinx" in v2
to properly match the manufacturer and board schematics.

Best regards,
Pufan Jin

Hi Andrew,

Thanks for the review. In v1, the mdio node and phy-handle were omitted,
relying on the Cadence MACB driver's MDIO auto-probing, which was 
incomplete.

According to the hardware schematics and live register readback, the board
has an on-board Micrel KSZ9031RNX Gigabit PHY strapped to MDIO address 1
(PHYAD[2:0] = 001b, PHY ID 0x00221620).

In v2, I have added an explicit mdio bus node with the PHY at reg = <1>:

```
     mdio {
         phy0: ethernet-phy@1 {
             reg = <1>;
             compatible = "ethernet-phy-id0022.1620";
         };
     };
```

and referenced it with phy-handle = <&phy0> under phy-mode = "rgmii-id".

This has been validated on physical hardware at 1000 Mbps Full Duplex
with zero CRC/frame errors.

Best regards,
Pufan Jin
